• Abstract: This chapter explores the zootechnical potential of edible insects as alternative ingredients in animal feed, with a special focus on Gromphadorhina portentosa. The growing demand for sustainable protein sources and the need to mitigate the environmental impact of conventional livestock have intensified interest in insects as a viable protein option. This review addresses the most studied insect species, their nutritional profiles, and their applications in feed formulations for fish, poultry, and other animals. In particular, studies on G. portentosa highlight its nutritional value, adaptability to plant-based diets, and potential for sustainable farming. Evidence suggests that this detritivorous cockroach can be efficiently reared on organic residues and holds promise as a protein source for animal nutrition.
